it is not dangerous in any way since it is just metal and metal oxides that do not mobilize at the temps you use for soldering. it is not recommended because the protective layer on most modern soldering irons is made from iron (not steel) and iron is softer than steel.
soldering iron is made from iron, got it..
So, all I need to do is find a soldering steel ๐ค
here is a schematic diagram with the structure: https://www.thermaltronics.com/datasheet/M8SB276#item38791
the core of soldering irons has been copper for a long time.
Thanks, that's very helpful
"Soldering steel: for when you want to weld something really, really small."
Are you certain? I seem to recall that steel wool burns. Iโm not sure how different the pictured scrubber is from steel wool pads.

a spark is typically hotter than 800ยฐC while soldering above 400ยฐC just isnt something you see for electronics. (brazing is another matter though)
Good point. My gut tells me that soldering temperatures won't be enough to cause this (the article talks about a spark). Anyway, not something I want to try out while soldering ๐
